Chemical Structure
Description
Lithium DL-2-Hydroxybutyrate (CAS 381716-41-2) is a high-purity analytical reference standard with the molecular formula C4H7O3Li and a molecular weight of 110.04 g/mol.
The molecular framework of Lithium DL-2-Hydroxybutyrate (C4H7O3Li) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
